A multipoint contact detection device includes at least two capacitive or inductive sensitive structures associated with respective primary detection zones of a surface that a person is likely to contact. The sensitive structures are positioned with a separation that is small enough between them to define at least one intermediate detection zone that the person is likely to contact while exerting a capacitive or inductive disturbance on the adjacent sensitive structures. The device also includes a processing circuit configured to detect, for each sensitive structure, a disturbance induced by the person coming into proximity or into contact and locating the region or regions of the surface with which the person comes into contact relative to the primary detection zones and the one or more intermediate detection zones.

An electronic control unit (ECU) may receive, from an autonomous vehicle controller, an instruction to set a hydraulic steering actuator, of a vehicle, to a particular machine steering angle setting. The ECU may provide, to a steering controller torque device, a current to set a steering controller, of the vehicle, to a particular steering controller angle that corresponds to the particular machine steering angle setting. The ECU may provide, to a hydraulic control system, a current to set the hydraulic steering actuator to the particular machine steering angle setting.

A vehicle position detector includes: a satellite positioning receiver; an autonomous navigation processor outputting an own-vehicle position as an autonomous navigation position; a determining unit determining occurrence of a position jump on the basis of a positional difference between the autonomous navigation position and a satellite positioning position detected by the satellite positioning receiver using satellite positioning; and a selector selecting one of the autonomous navigation position and the satellite positioning position on the basis of positioning precision of satellite positioning output by the satellite positioning receiver, and a result of the determination, wherein the vehicle position detector outputs one of the autonomous navigation position and the satellite positioning position as the own-vehicle position on the basis of a result of the selection.

Provided is a steering assist apparatus configured to perform a steering assist control for changing a steering angle of a vehicle in such a manner that the vehicle moves along a target path; determine whether a newly-detected object is a stationary object or a moving object; cancel the steering assist control and inform a driver that the steering assist control is cancelled when the newly-detected object is the stationary object and a cancel condition is satisfied; pause the steering assist control and inform the driver that the steering assist control is paused when the newly-detected object is the moving object and a pause condition is satisfied; and resume the steering assist control when a resume condition is satisfied.

A driving support device performs steering control and deceleration control for avoiding an object which is detected in front of a host vehicle. The driving support device performs: calculating a target lateral distance which is a target of the steering control and which is a lateral distance between the host vehicle and the object when the host vehicle passes by the object; and increasing target deceleration which is a target of the deceleration control and which is deceleration of the host vehicle when the host vehicle passes by the object as a lateral distance restraint value which is obtained by subtracting the target lateral distance from a threshold value increases when the target lateral distance is less than the threshold value.

In the present disclosure, a turning control method for a construction machine, a construction machine and a computer device are provided. The turning control method includes: acquiring position information of an initial position and a target position as well as kinematic parameters of the construction machine; determining a turning curve according to the position information and the kinematic parameters; and controlling the construction machine to travel from the initial position to the target position according to the turning curve, wherein a portion of the turning curve in which curvature thereof varies is a transition curve. In this way, the construction machine can achieve continuous changing in curvature during turning, without a spot-turning phenomenon.
